Performance Problems

hi,i have one server with serious performance problems.

The Availability Index is about 18 but network, ram, disk and cpu utilization are ok!?

We use an IBM Blade Center:

HS20: 2 Dualcore CPU’s 4GB Ram

DS 4200: two 500 GB SATA HDD in a Raid 1

OS: Windows 2003 R2

Domino: 7.0.3, Domino Cluster

Whats the Problem? its not only the AI - i know that it can be configured with the extension factor - also the users report really bad response times…

Can anyone explain me the Server.LoadMon.TransInfo.RunningAvgTime - how is it calculated?

i thought that its an average of alle values beginign from the last server start but i think thats wrong - i checked this values for about 3 minutes:

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 43

Server.LoadMon.TransInfo.MinAvgTransTime.CLOSE_DB = 55,6

Server.LoadMon.TransInfo.RunningAvgTime.CLOSE_DB = 3.687,4186046512

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 51

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 52

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 96

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 43

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 40

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 66

Server.LoadMon.TransInfo.CurrentTransCount.CLOSE_DB = 68

Server.LoadMon.TransInfo.MinAvgTransTime.CLOSE_DB = 55,6

Server.LoadMon.TransInfo.RunningAvgTime.CLOSE_DB = 4.260,75

you can see the current values are lower then 100 but the runningaverage is growing!?

thanks

Hi,

Frequently Asked Questions - Server Availability Index (SAI) in Domino 6.x and 6.5x it’s for R6 but i’s good too.

What have you done to isolate your performance problems?

Slow database performance due to unread marks

hi,thanks for your response!

I know this documents - i used perfmon to find out if there are some bottlenecks - here the average values of one day:

Memory:

pages/sec=510,3 => i think its OK

Network:

Bytes Total/sec *8 / 100Mbit = 0,04% => OK

Disk:

Disk Queue Length/Spindles = 0,3951 => OK

CPU:

% CPU Time = 8,36 % => OK

i think this key Indicators are ok - did i miss some important indicator?

thanks

I tend to the application side of things, so I’d look at what might be making applications slow. It might be poor choices made when writing code, or that an application is far exceeding original estimates of usage, etc.

I like to enable view index logging and agent manager logging for a day, and then see if those numbers seem out of whack. It doesn’t always tell you what the problem is, but I frequently find that they do help quite a bit.
